X-RAY APPARATUS.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed May 25, 1908. Serial No. 434,885.

To all whom it may concern:

Be it known that I, WILLIAM S. FULLER- TON, a citizen of the United States, residin at St. Paul, in the county of Ramsey an State of Minnesota, have invented a new and useful X-Ray Apparatus, of which the following is a specification.

My invention relates to X-ray apparatus.

It has for-its object a machine of convenient construction for use in X-ray fphi;-

a normal conditions in patients, and particularly to the adjustment of the X-ray apparatus to the patient without inconvenience to the latter while a stereoscopic photograph is secured. It facilitates quick and comfortable adjustment to the patients body,

and permits the correct stereoscopic alinement of the tube on each side of the central vertical line.

In the drawing Figure 1 is a side elevation of my machine, Fig. 2 is .a front elevation of the same, with the base cut away.

Fi 3 is a detail showing the tube-holder an shield, stereoscopically "adjusted on either side of a central vertical line. Fig. 4 is a detail cross section of Fig. 2 taken on the line zv-m.

The tube-holder 1, shield 2, and diaphragm 3, are carried on an arm 4:, which is attached to a head 5, adapted to move vertically upon a tubular standard 6. The head slides freely upon the standard, and is counter poised by means of the weight 7, connected y the cords 8, with the head 5. Said cords pass freely over the pulleys 9. The compression lever 10' is bifurcated at its inner end, the bifurcations being united at their extremities to form the bow 10 which is pivoted u on the head by means of the pintles 11. link '12 connects the bow of the compression lever-with an offset 13 provided upon the ring 14, which is snugly but movably fitted upon the standard 6. The ring 14: thus serves as a sliding fulcrum, which, when force is applied to the handle of the lever 10, cramps on the standard 6 and affords successive purchase points. It will be obvious that a vertical manipulation of the handle of the lever will thuspermit a step by step lowering of the head upon the stand-' ard, and a like depression of the tube-holder and other parts carried by the arm 4. The frame 15, adapted to carry the tube,

shield and diaphra In, is suspended from the arm 4 by means 0 the lock rings 16, to permit a rotary motion around the arm, by which the tube may be directed to any osition on either side of the arm, ranging mm the vertical to the horizontal, and-this lock ring 16 is retained in the desired position by the clamps 17 By loosening the clamps, it is also obvious that the tube, shield and diaphragm may be moved horizontally upon the arm 4, either toward or away from the standard. Thus the frame 15, and the X- ray tube Whichit carries, may be moved, and secured against movement, both hOIlZOIltally and rotatably upon the arm.

The frame 15 is provided with the guide arc 18, upon which the casing 19 is adjusted to slide to the right or left, as distinctly shown in Fig. 3. This movement upon the arc is made after the vertical and horizontal adjustment of the light to the patients body for the purpose of securing two photographic exposures for the pictures to be used 111 a stereoscopic reproduction, as will be readily understood by those skilled in the art. The casing 19' is bolted to the rods 20 which carry the tube, shield and diaphragm. The lockscrew 21 is provided for the purpose of securing the tube at the desired,

either side.

The standard 6 is supported by the base 22, mounted upon ball bearing casters23, to facilitate moving the entire instrument so that it-may be quickly and comfortably adjusted to the patients body as he lies on an ordinary lounge or bed, instead of requiring him tobe lifted and placed in the apparatus, as is the case with other devices for similar purposes.

It will thus be apparent that my invention possesses great mobility of adjustment; that the entire instrument may be conveniently placed in position for use, and that the diaphragm may then be applied to the organ under inspection, by horizontal, vertical and radial ad ustment so as to secure the best results in X-ray photography.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a device of the class described,a support for an X-ray tube comprising a standard and arm movable vertically thereon,

an are carried by the arm, a sliding member supported by the arc and adapted tomove radially on both sides of a vertical line passin through the center of the arc, and a tugs holder suspended from the sliding member.

2. In'a device 'of the class described, a

- standard provided with a base, an arm and ringboth slidably mounted. upon the standard, a fulcrum supported by the ring, a

lever having a link connection between'the ring and fulcrum, anare suspended from the arm and a tube holderwsuspended from the are by means adapted to slide radially thereon. Y-

3. In a device of the class described, the combination of a tubular standard, a head slidably mounted thereon and counterpoised by means of a weight in the standardi a 2O lever pivoted u on the head'and provi ed with a sliding ulcrum upon the standard, a horizontal arm carried by the head, a

' tube-holder and shield suspended from said prising in combination a tube-holder, a

arm, and means for moving and adjusting the tube and shield radially and horizontall upon the arm, all for the purposes specifie 4. A device of the .class described, come frame extending in the form of anoarc an equal distance on each side of lts vertical center,' a hanger for the tube-holder ada ted tomove radially in the frame, a stan ard providedwith a base, and means for supporting and moving the frame upon the standard.

5. In a device of theclass described, the

combination of a tubular standard, a head slidably mounted thereon, a counter-weight for the head, Within the standard, a horizontal arm carried by the head, a tubeholder and shield suspended from said arm, alever pivoted upon the head, and a sliding ring upon the standard, connected with the lever and adapted to act as a fulcrum therefor.

6. In a device of the class described, the

frame being suspended from the arm, and,

means for movin the tube-holder in an arc, whereby the ano e of the tube will maintain. the same focus on each side of a central vertical line. v

In testimony whereof I have signed my a counter-weight name to this specification in the presence of two subscribing witnesses. I
